EM radiation (watts?)

Does a machine that uses 500W emit more em radiation shit than a device that only uses 250W? also where is the source of the radiation, is it through the power outlet where its plugged in, and if it is, the further away from the power outlet one is the less exposure to radiation one will experience?

Now, EM radiation is basically anything from longwave radio, microwaves, through visible light to gamma radiation....But still it's hard to say whether a 500W device will generate more EM radiation than a 250W device. Wattage itself is a measure of how much *energy* is released. Energy in itself can be released in other forms than EM radiation, like kinetic energy.

In some cases it's true, A stronger lightbulb, radio transmitter or microwave oven will release more EM radiation than a weaker one - on the other hand, the very purpose of those are to generate EM radiation (microvave radiation, radio signals and visible light respectively).

Compare, however, two very different devices, and you'll see it's not entirely true.A car engine, for example will likely emit less EM radiation than a microwave, as its primary function is to generate kinetic energy. Car engine power can be measured in the range of kilowatts (thousands of watts) compared to the microwave oven, which is usually 1 kW at most.

Now, even a relatively weak car engine outputs around 100kW - a hundred times more than the microwave oven, probably 80% of that goes to moving the car, while 20% is released as heat (which can be released either as EM radiation or be conducted though various materials eg. air, water or metal). Comparatively less energy goes to generating EM radiation in the car engine than in the microwave oven, as again ,the purpose of the latter is to actually generate EM radiation of a certain frequency in order to excite the water molecules in the food.

>em radiation shit

Don't fall into that ballpark... our universe is dominated by EM radiation - you'll never be free from it :)
